I'm not sure I follow: are you suggesting to write a function named
w32_adjust_shell_and_set_mode_flags that would search for SHELL along
PATH, like find_and_set_default_shell does now?  That'd be a terrible
cycle killer, because this function would be called on each command
invocation.

Or am I missing something?
